What is NotebookLM?
NotebookLM is Google's AI research and note-taking tool. You build a notebook by adding sources like PDFs, Google Docs, Slides, websites, YouTube videos, and audio files. Then you ask questions and get answers grounded only in those materials, with citations you can click to verify.
To use it, sign in with your Google account, create a notebook, and upload or link your sources. Once added, you can ask questions in plain language. The tool also turns your sources into Audio Overviews—podcast-style conversations—plus video overviews, mind maps, study guides, flashcards, and briefing documents.
It suits students, researchers, and professionals who need to work deeply with specific documents. The tool is free with a Google account; Google AI Pro and business plans raise the limits. The website does not state exact usage caps for the free plan.
